The design and testing of bituminous mixtures includes various laboratory tests as, for example, the Marshall stability (EN 12697-34), the Gyratory compaction (EN 12697-31), the Slabs laboratory compaction to prepare specimens for Wheel tracking (EN 12697-22), Determination of stiffness including Beam fatigue testing (EN 12697-26, EN 13108), etc.
To produce the samples to perform the above tests it is essential the preparation of a bituminous mixture, at a reference temperature within a time that is limited in order to reduce mechanical degradation of the aggregates. The mixer shall also be capable of entirely coating all mineral substances in not more than 5 min as prescribed by EN 12697-35.
The PAVELAB BITUMIX Automatic Laboratory mixer fully satisfies the Standard requirements.
 
The mixer consists essentially in a horizontal stainless steel mixing container with helical mixing shaft. The container is thermally insulated and complete with heating element and probe sensor which provide uniform temperature control. The container can be easily tilted for unloading operation by an electric motor.
The control panel includes a digital display to monitor mixing temperature, the digital thermoregulator, the mixing speed controller and commands.
